HVAC and Air Purification
You can of course pay a professional HVAC contractor for a system that's appropriate for your shop.
If that's an option for you, go for it. Chances are that it'll be a well planned system that will create a comfortable and safe environment for you for years to come.
If you need a more affordable solution or you just need something sooner, we've lined up a few great options for you but there are a few things to consider for your own safety first.
Your wood shop is packed with flammable materials and vapours. Choose your heater wisely. No naked flames and no heater elements that could potentially ignite something.
If a professionally fitted HVAC system isn't within budget, a decent oil heater will safely and economically heat a room up to around 150 square feet.
There are other ways to heat a garage that isn't being used as a wood shop with a single garage heater but they carry a risk of igniting dust so we don't recommend them.
Cooling is a much easier topic to solve because a typical portable AC unit isn't going to blow the roof off your garage. Well, we'd hope anyway.
If you live in a climate that's hot for most of the year, AC will be a priority. Working in 100*F is not fun so what do you do?
Again, assuming a professionally installed HVAC system isn't on the table, a portable AC unit will work perfectly, just as long as you've insulated your garage properly...
Here are some candidates that will do the job for you.
A decent air filter in your wood shop makes all the difference in the world.
Typically, you just attach a few hooks to the ceiling, lift your new machine into place and plug it in. Most of them are remote controlled and have multiple speed settings.
You should look for a quiet 50 to 60 decibel machine that's capable of filtering down to 1 micron.
A timer is a handy feature too so you don't have to worry about leaving your filter running after you're done for the day.
Best of the rest...
